More than 160 people have lost their lives, and several have been injured since ethnic violence broke out in the state on May 3 when a 'Tribal Solidarity March' was organised in the hill districts to protest against the Meitei community's demand for Scheduled Tribe (ST) status.

In a tweet, Sibal said, "The only way forward: Sack Biren Singh; Impose Art. 356; Apologise to the women of our country." "Nothing has changed since Nirbhaya: Unnao, Hatharas, Kathua, Bilkis (convicts release). Beti bachao PM ji!" Sibal said.

According to Article 356, President's rule can be imposed in a state if a situation has arisen in which the government of the state cannot be carried on in accordance with the provisions of the Constitution.

Tension further mounted in Manipur on Wednesday after a May 4 video surfaced online showing two women from one of the warring communities being paraded naked by a group of men from the other side. Meiteis account for about 53 per cent of Manipur's population and live mostly in the Imphal Valley, while tribals, which include Nagas and Kukis, constitute 40 per cent and reside mostly in the hill districts.

Sibal, who was a Union minister during the UPA-1 and UPA-2 governments, quit the Congress in May last year and was elected to the Rajya Sabha as an Independent member with the Samajwadi Party's support. He recently floated the non-electoral platform 'Insaaf', aimed at fighting injustice.
